Anal glands are located on either side of the anus and normally produce secretions that are pushed when feces is evacuated from the rectum. An anal sac tumor is a tumor of made up of cells originating from the glands of the anal sac. These tumors can spread and therefore staging is recommended prior to surgery. To diagnose these tumors, a fine needle aspirate can be placed from the outside and. Early detection of anal gland cancer in dogs is best followed with aggressive treatment. If the tumor was discovered in the early stages and the spread to lymph nodes is limited, complete removal of the tumor is desirable. If a veterinarian palpates an anal gland mass, further testing will be recommended, including blood & urine tests to evaluate the health of major organs and check for hypercalcemia. Aspiration of the anal gland mass a minimally invasive test that involves using a vaccine-sized needle to collect cells from the anal gland tumor. The recommended treatment for anal gland tumors is complete surgical excision followed by chemotherapy (e. Carboplatin or mitoxantrone) in order to prevent or slow the onset of metastasis. For cases in which complete surgical excision cannot be obtained, follow-up radiation therapy is recommended to control local disease. Tumors of the anal sac are uncommon a represent a small percentage of all tumors in dogs (1). The most common malignant tumor of the perianal region is the anal sac (gland) carcinoma accounting for 16. Adenocarcinoma is the most common cancerous anal gland tumor in dogs. Its a very aggressive cancer and has a high probability of metastasizing (spreading) to the lymph nodes and other organs. The recommendation for treatment is surgical removal as soon as possible. This surgery is tricky and does not have a high success rate, if not done properly.
